The thing is that I have four styles I have created in QGIS through the GUI and saved into a postgresql database.
I can see them in the table named layer_styles
I have seen similar questions asking to load from qml file, or even from a database, like thatlike that but it looks as if I need to get a styled layer before for get the style from it.
It's like I say or can I load the styles from database without a styled layer?
Anyway I don't know how must I do to get the styles and use it for another layers
